Who wants to try to teach me about them? I have a very difficult assignment to do, that I am finding incredibly hard, I don't really understand them!
Any help you could give would be useful, I understand the Sun, Planets, Arm, Ring configuration, but thats about it

Auto boxes use epycyclic gearing Tom.
They use brake bands to lock gears up in sequence in order to change ratio if I remember correctly.

One thing I am struggling to understand is that there is a shaft attached to the arm, and another to the sun gear.
What happens if either the arm or the sun is locked in place? As there is then only one shaft, to either input a torque, or output it.
Therefore the ring must be used as either an input or output in this situation, but how? Everywhere I look online, nobody mentions using the ring gear to transmit a force.
